'TWYE'R-BUSHING.

vTo (LZL whom t may concern' Be it known that I, FRANK KLEPETKO, acitizen of the United States,residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Twyer-Bushings, of which rhe followingis a full, clear, and exactdescrip- "on. reference being had to the accompanying drawingss, forming a part hereof.

.VIy invention has relation to improvements IA t \vycr-bushing; and it consists in the novel construction of bushing more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 isa vertical transverse section of a water-jacket on line 1 1 of Fig. 2, showing my invention applied thereto. Fig. 2 is an elevation of one-half of a waterjacket broken above the twyers. Fig. 3 isa sectional detail of a twyer of a shallow jacket, showing my invention applied thereto. Fig. 4 is asimilar-view showings modified'form of bushing; andFig. 5 is a similar sectional detail of an ordinary nipple-twyer, showing my invention applied thereto.

The object of my invention is to construct a bushing for insertion into a fu rnace-twyerto protect the wallsof thtwyer against injury by the punchingbar, the frequentuse rof the latter in the barring of the furnace often resulting in injury to the twyer-Walls and joints thereof if left unprotected.v

In providing atwyer with a bushing for the specific purpose here referred to the construction of said bushing should be such as to prevent the same from slipping inwardly or out.- wardly in punching the twyer. To this end I have devised a bushing which whi le specially applicable to twyers Whose bounding-walls are formed or expanded from the inside and outside sheets of the water-jacket of which said twyers form a part, the said bushing is equally applicable to the prevailing style of ordinary nipple-twyers.

In detail the invention may be described as follows: A

Referring to the drawings, and particularly to Figs. l to 3, inclusive, 1 represents the inside sheet, and 2 the outside sheet ofthe water-jacket. At points where itis desirable to locate a twyer the inside sheetis punched and anged outwardlythat is, toward the outside sheet-there being thus formed an opening bounded bythe inwardly-Haring nipple 3. Opposite the nipple 3,01t the inside sheet the Specification of Letters Patent.

outside sheet has punched and flanged inwardly therefrom an outwardly-flaring nipple 4 of compound sectional curvature, the open ing of said nipple4 receiving the adjacentend of the nipple 3 and forming a tight joint therewith, the edge of the metal of the nipple 3 being expanded subsequently against the outer face of the nipple 4, thereby for'ming an expanded ring or head 5, insuring a tight joint. For jackets of moderate depth the end or edge of the nipple 3 is passed through an opening formed in the original wall of the outside sheet, as shown in Fig. 3, the end of the nipple being expanded against the outer face of said outside sheet` as in the form shown in Figs. 1 and 2.' The twyer herein described I do not claim; but the same is alluded to, since my improved bushing is specially applicable thereto. This bushing comprises in one ofv its forms a tubular ring 6, having an inner peripherally expanded or flanged end 6', the outer end of the ring being preferably screw-threaded and provided with an annular ring or head 7, which in Figs. 1 and 2 rests in thedepression'formed by the inward Hanging` of the nipple 4. In Fig. 3a similar head 7' is screwed. to the outer projecting end of the ring 6. The annular head' 7 (7') when once attached to the ring 6 virtuallyforms a terminal ange whichoverlaps the opening of the twyer, thus preventing the slipping ofthe bushing inwardly. The inner l enlargement or flange 6' prevents the bushing from slipping outwardly, so that during the barringopelationthere is absolutely no danger of displacement of the bushing -from its position iu the twyer. The part 7 (7') also protects the joint at the outer end of-the nipple 3 against injury from the punching-bar during the barring operation.

Theinner terminal peripheral enlargement, which in` the foregoing types of bushing as -suines the form of an expanded ange 6', may

be in the form of an annular ring or head 8, screwed (or otherwise secured) to the inner end of the tubular ring 6, as shown in Fig. 4, the outer wall of said band 8 Haring so as to conform to the curvature of .the base of the nipple 3.

As beforestated, thepresent bushing, while specially applicable to the flanged .form of twyer already described, maybe used in the ordinary nipple-twyer, as shown in Fig. 5. In said figure, 9 4represents the ordinary nipple-twyer. The form of bushing specially applicable thereto is like that shown in Fig.

A 3, comprising a tubular ring 6, an inner parent that I may depart in a measure from the details hereshown without in any Wise affecting the nature or spirit of my invention. Neither do I Wish to limit its application specially to twyers.

Having described my invention, what I claim isl. A tWyer-bushing comprising a tubular ring having an inner terminal peripheral enlargement, and an outer terminal head adapted to span the opening of the tWyer, substantially as set forth. Y

2. A tWyer-bushing comprising a tubular ring having an inner terminal peripheral in- Wardly-aring flange1 and an outer terminal head adapted to span or overlap the opening of the twyer, substantially as set forth.

3. In combination with a Water-jacket having an insideV and an outside sheet and prou vided with a twyer having an inwardly- Haring nipple leading from the inside sheet and coupled to the outside sheet, a bushing composed of a tubular ring having an inner terminal peripheral enlargement following substantially the contour of the nipple, and an outer terminal head spanning the opening of the twyer, substantially as set forth.

4. In combination with a Water-jacket having an inside and an outside sheet and provided With a twyer having an inwardlyflaring nipple leading from the'inside sheet and coupled to the outside sheet, a bushing composed of a tubular ring having au inner terminal inwardly-aringlianged portion conforming substantially to the curvature of the nipple1 and an outer head spanning and over-` lapping the opening of the twyer, substantially as set forth.

5. A tWyer-bushing comprising a tubular ring having an inner terminal enlarged peripheral flaring portion` and an outer head or flange1 substantially as set forth.

6. A tWyer-bushing comprising a tubular ring having 4an inner terminal fiange daring beyond the peripheral Walls of the ring, and an outer terminal head or flange for overlapping the tvvyeropening` substantially as set forth.

7. In combination With a Water-jacket having an inside and an outside sheet, and provided With a twyer having an inwardly-Haring nipple leading from the inside sheet and coupled to the outside sheet, an annular ring or head located in front of and protecting the outer end of said nipple, and means for retaining said head in position, substantially as set forth.

8. In a'Water-jaolret having an inside and an outside sheet, a nipple extending from the inside to the outside sheet, and a protecting ring or head carried in front of the outer end of the nipple, substantially as set forth.

. 9. In a- Water-jacket having an inside and an outside sheet, a nipple connecting the sheets, and a protectingring located in front of the joint formed between the nipple and outside sheet` substantially as set forth.

In testimony whereof I' aiix my signature in presence of tWo Witnesses.
